Description
Technical field
The present invention relates to engineering and material science, remanufacture the preparation method of coating particularly to a kind of cylinder liner internal wall.
Background technology
Cylinder liner is most to be vulnerable to infringement as in electromotor important parts, reduces or reduces infringement and seem
The most necessary.The modal failure mode of cylinder cylinder sleeve is wear out failure, mainly include abrasive wear, corrosive wear and
Adhesive wear.It is taken as that the internal combustion engine of quovis modo, the requirement to its cylinder jacket is substantially consistent, i.e. cylinder jacket
Inner surface must meet the low-friction coefficient between high abrasion resistance and piston ring, corrosion resistance, wearability and enough
Tensile strength etc..
Before making the present invention, people use many ways to attempt to improve its wearability etc..Wherein, just there is plasma spray technology.
Plasma spray technology is to utilize thermal source that sprayed on material is heated to melted or semi-molten state, makes it change by air-flow at a high speed former
Some states, are molten into drop, are ejected into the material surface through pretreatment, form the surface layer of adhesion-tight.Thermal spraying is
Cylinder jacket remanufactures one of technique, thermal spraying can at cylinder inner wall spray-on coating to recover cylinder jacket size, coating material with
Coating structure can to a great extent in regulation and control, the hole in coating can realize oil storage function.
Ceramic powders adds the effect that can play hard phase in coating, improves the anti-wear performance of coating.Thermal jet is utilized to prepare
Composite coating is an up the effective way of coating performance, and existing spraying method great majority are simple mixed-powders, when multiple
When powder density difference is bigger, spraying process often cause coating to be divided because of mixed-powder acceleration difference in thermal spraying flame stream
Layer phenomenon, this is also one of key factor restricting composite coating development, particularly evident when metal mixes with ceramic powders.At present
Conventional solution is the non-ceramic powder product as an alternative using density difference less, and this method is difficult to reach preferable
Abrasion resistant effect；Or spraying is through the cladding powder of processing, this method due to needs spraying front by metallic cover nonmetal
Powder surface, powder preparation cost is higher.
CN101250698 invents a kind of composite corpuscle nickel base alloy manufacture or the method for repairing cylinder cover, for railway,
Peculiar to vessel and large power diesel engine cylinder jacket is the reparation of inwall after using abrasion.Use chemical mode by alloy solution, be coated in
Interior surface of cylinder liner, coating process is: goes out to add in the composite corpuscle nickel base alloy solution of a device imports cylinder jacket to be processed and
Silicon-carbide particles in solution are coated with at interior surface of cylinder liner to be processed, then import condenser by row chemical reaction equably,
Making solution lose activity, chemical reaction stops, and pumps into liquid pool dosing, is re-fed into heater, arrival outlet temperature 82～83 DEG C
Rear importing adds a device, adds silicon-carbide particles and be configured to the circulation that composite corpuscle nickel base alloy solution entrance is following within adding a device
System.Although this technology can manufacture reparation smoothly on workpiece, but there is the biggest defect of environmental pollution or problem,
Additionally, due to technique this technology rehabilitation cost excessively complicated is too high, hardly result in extensively application.
CN103710660A relates to a kind of engine water-cooling cylinder jacket outer wall and inner wall size is recovered and intensifying method.The party
Method is to use internal plasma spraying technology to prepare Ni-based anti-attrition, wear-resistant coating at cylinder liner internal wall, uses supersonic speed plasma
Spraying technology prepares nickel Aluminium composite coating at cylinder jacket outer wall.Sprayed on material can only the high Ni bag Al powder of use cost, material
Material wearability is limited, also without reference to the preparation of composite coating.
CN103132009A is the method for the inner surface of the cylinder sleeve that a kind of reparation is contained in engine cylinder-body.From inner surface
Removing material, to produce the region that thickness reduces, the region that thickness reduces axially extends relative to cylinder, and not up to
The end of cylinder sleeve stops, thus leaves initial diameter district between region and the end of cylinder body that thickness reduces.Then, such as
The rough surface in the region making thickness reduce is brushed by hammer.This Patent Office is limited to the reparation of size, selects at material and adds
It is not carried out in work technique breaking through.
Summary of the invention
